Roger slept soundly, despite his new surroundings, and the night seemed all too brief for him when he was roused by the cook. Being February, the days were short, and though it was nearly seven o'clock when the camp was wakened it was almost full dark. But few minutes were allowed before George shouted, "Breakfast," and Roger fell to with the rest of the men, feeling as though he could eat the entire provision of the party at one meal. After breakfast, Rivers told the boy that he would be expected, at the breaking up of camp in the mornings, to help Harry, the Indian, in the harnessing and getting ready of the dogs, as most of the other men were more expert at loading a sled. It sounded easy enough, but Roger soon discovered that it was far from being a snap. To harness a dog, or even a dozen, was not such a difficult matter, but to hitch them to the sled and to make them stay where they were after they were hitched, that was another question. The "huskies" seemed to take malicious joy in trying to get their harness tangled, and there was always the possibility of a scrap to be warded off. So it came about that the boy usually had his hands full in the morning, and was not sorry when the day's pulling was begun and the dogs settled down to their work. The country over which they were traveling, moreover, was ideal for dog work. The land was flat from the waterside up to the sudden rise of the hills, which were lofty and rugged, 10,000 to 15,000 feet in height, snow-capped and glacier-bearing. Little though Roger knew as a geologist, yet he was keen enough to see that this wide channel must be the delta of a large river, and he was glad to get an affirmative response to his suggestion that in the summer time this might be a good agricultural country. "The climate in summer here," said Gersup, whom Roger had asked the question, "is nothing short of heavenly, but you could hardly call it thickly settled as yet." "But it will be some day? Do you suppose?" "Most assuredly," answered the topographer. "There are thousands upon thousands of acres of land here, which would return immense crops, and all along up the river. All that is needed is a market for the produce." "But how about moving it?" asked the boy. "The Sushitna River is navigable for a hundred miles to steamers of light draught, and to barges. You'll see this all in farm like the Red River Valley some of these days."
